A possible ring ditch is visible on aerial photographs of 1992 as a cropmark circa 300 metres to the north-east of Netherexe Barton, Nether Exe. The visible cropmark is less than 2 metres wide and encloses an area approximately 18 metres in diameter. The cropmark is possibly evidence of a round house of later prehistoric to Roman date. The cropmark falls within the area of a much larger possible ditched enclosure, of possible Bronze Age or earlier date, but with which it might be associated.
